Table 1. NI PXIe-6124 Specifications Overview
Overview and Applications
The NI PXIe-6124 S Series multifunction data acquisition (DAQ) module
offers simultaneous sampling at 4 MS/s per channel, 16 bits of resolution,
and a PXI Express interface for dedicated bandwidth from module to
controller. The module features high speed and resolution that suit a
variety of applications such as:
• Highly transient signal acquisition
• Ballistics and impact testing
• High-energy physics
• Ultrasonic and sonar testing
Features
Simultaneous Sampling – The NI PXIe-6124 samples its four analog
inputs simultaneously with a dedicated 16-bit analog-to-digital converter
(ADC) per channel. Simultaneous sampling has several benefits:
• High sampling rate on all analog input channels
• High aggregate data throughput
• No interchannel delay
Multiplexed devices share one ADC among multiple channels, keeping
the aggregate data throughput constant regardless of the number of
active channels. For simultaneously sampling devices, the aggregate
data throughput increases linearly with the number of active channels
and selected sampling rate, up to 16 million samples per second
for this device.
Simultaneous sampling devices also preserve the phase relationship
between input signals and do not have an interchannel delay introduced
by a multiplexer.
PXI Express Interface – The NI PXIe-6124 features a x1 PXI Express
interface and is compatible with x1 and x4 PXI Express slots or PXI Express
hybrid slots.
Where PCI and PXI share bandwidth among the modules, PCI Express
and PXI Express provide dedicated bandwidth to each module, which
means you can have several modules streaming data to and from the
controller without resource contention. The NI PXIe-6124 also features
six DMA channels, so you can use the analog, digital, and counter
functionality with minimal CPU interaction.
The PXI Express bus delivers the industry’s best synchronization and
latency specifications. For more information on PXI and PXI Express,
visit ni.com/pxi.
High-Speed Stream to Disk – With the high bandwidth provided by
PXI Express, it is possible to stream hundreds of megabytes of data per
second to disk. For more information on the best hardware and software
to use for streaming, visit ni.com/streaming.
S Series Simultaneous Sampling Multifunction DAQ – 16-Bit, 4 MS/s per Channel, 4 Analog Inputs
Better Dynamic Specifications – The analog input path on S Series
devices is tuned for both accurate DC and dynamic measurements, while
multiplexed data acquisition devices suffer from settling time and
distortion error created by switching the input channel.
Many Input Ranges – You can configure each analog input channel
to use one of four voltage ranges, from ±1 to ±10 V. By selecting the
input range most appropriate for your signal, you maximize the available
16 bits of resolution.
Signal Conditioning – With the release of NI-DAQmx 7.4, all S Series
devices are compatible with parallel mode SCXI modules.

Table 2. Most Commonly Used Parallel-Mode SCXI Modules
Although you can sample signals through an SCXI module at up to
4 MS/s, the SCXI module reduces the available analog bandwidth.

Recommended Software
National Instruments measurement services software, built around
NI-DAQmx driver software, includes intuitive application programming
interfaces, configuration tools, I/O assistants, and other tools designed
to reduce system setup, configuration, and development time. National
Instruments recommends using the latest version of NI-DAQmx driver
software for application development in NI LabVIEW, LabWindows/CVI,
and Measurement Studio. To obtain the latest version of NI-DAQmx, visit
ni.com/support/daq/versions. NI measurement services software
speeds up your development with features including:
• A guide to create fast and accurate measurements with no
programming using the DAQ Assistant
• Free LabVIEW SignalExpress LE data-logging software
• Automatic code generation to create your application in LabVIEW;
LabWindows/CVI; LabVIEW SignalExpress; and Visual Studio .NET,
ANSI C/C++, C#, or Visual Basic 6.0
• Multithreaded technology for 1,000 times performance improvements
over basic data acquisition driver software
• More than 3,000 free software downloads to jump-start your project
available at ni.com/zone
Easy Multidevice Programming – NI-DAQmx driver software now
supports multidevice tasks for S Series. Synchronizing channels on
multiple devices using the RTSI, PXI, or PXI Express bus is now as simple
as configuring a single data acquisition board. This greatly reduces the
time and complexity involved with multidevice application programming,
and is now available for any combination of S Series devices.
